PURPOSE:To prevent discontinuity or shock of transmission by storing a NULL value (ratio fixed value and the like) of a solenoid to one driving frequency, and by carrying out control so that a difference between the one driving frequency and the NULL value is corrected when the driving frequency is switched over. CONSTITUTION:An aimed transmission control engine rotational frequency NESPRF is calculated 200 based on a throttle opening THRT, an output rotational frequency NCO and an engine rotational frequency NE, and the calculation result is multiplied 202 by a proportional gain Kp, which is transferred to a limitter 204. The output of the limitter 204 is integrated 206, while a nominal NULL value of a driving frequency 100Hz is determined based on an oil temperature TEMPS by a map 208, and a new output signal is calculated based on an output signal consisting of the NULL value and the value after the integration process 206 and on the output signal of the limiter 204. A difference between the driving frequency 100Hz and the NULL value of the other driving frequency is determined by a map 210 based,on the oil temperature, and when the driving frequency is switched over, the output signal is corrected so as to eliminate the difference. |
